佛甲草对小鼠缺氧耐受性的影响

目的：观察佛甲草提取液对小鼠四种不同类型缺氧耐受性的影响。方法：采用常压耐缺氧法、对抗特异性心肌缺氧法、对抗亚硝酸钠法及对抗脑缺血缺氧法观察小鼠存活时间。结果：佛甲草提取液延长小鼠在常压缺氧、特异性心肌缺氧、亚硝酸钠中毒性缺氧及脑缺血缺氧条件下的存活时间。结论：佛甲草提取液显著提高缺氧小鼠的耐受力。

The Effects of Sedum Iineare Thunb on Oxygen-deficient Endurance in Mice

Objective:The effects of the solution isolated from sedum lineare thunb were observed on oxygen deficient endurance induced by 4 Kinds of anoxia models in mice.Mehods:The studies on tolerating anoxia in mice were carried out by the test of the tolerance to anoxia under normal pressures,by the test of the specificity myocardium under hypoxia,by the test of the antagonism of sodium nitrite,and by the celebral hypoxia ischemia test.Result:The extracts of sedum lineare thunb prolonged not only the duration of tolerance to anoxia under normal pressures,but under the specificity myocardium hypoxia,and under the celebral ischemia,and prolonged the duration of the histotoxic hypoxia induced by sodium nitrity.Conclusion:The extracts of sedum lineare thunb increased their oxygen deficient endurance.
